More like *most* lights in reality *are* surfaces. Putting a 
light_source on a surface does nothing to imitate this.
And there are many cases where no surface is involved. Fire, for example.

Also, in reality, there is no such thing as a point light source. They 
only exist because they are so much faster to compute.
